The ParseFilterData method unpacks the binary registry data for a filter.

There is typically no reason for an application to call this method. The IFilterMapper2::EnumMatchingFilters method provides a more convenient way to access the filter registry data.


HRESULT ParseFilterData(
    BYTE *rgbFilterData,
    ULONG cb,
    BYTE **prgbRegFilter2



[in]  Pointer to the binary registry data.


[in]  Specifies the size of the binary data, in bytes.


[out]  Address of a variable that receives a pointer to the unpacked data. When the method returns, cast this pointer to a REGFILTER2 type to access the filter data. The caller must release the memory by calling the CoTaskMemFree method.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an error code.


Include fil_data.h, which is located in the Mapper Sample directory.
